What it is

1The CMS Medicare Part B ASP NDC-HCPCS Crosswalk: each Part-B HCPCS (J-code etc.) mapped to the NDCs billable under it, with labeler/drug name, HCPCS dosage, package size/qty, and billing units.
2This is the drug-IDENTITY bridge previously flagged missing — it lets a J-code resolve to its NDC set (drug_silver.dim_drug.ndc11) and an NDC resolve back to its HCPCS (vlada_curated.dim_code.code), unifying the drug catalog with the medical/HCPCS graph.

Raw door	Athena (read-only via query_substrate): drug_silver.fact_asp_ndc_hcpcs_crosswalk (filter is_current = true). hcpcs_code JOINs vlada_curated.dim_code.code (measured 850/850 = 100%); ndc11 JOINs drug_silver.dim_drug.ndc11 (measured 7,140/7,189 = 99.3%). NDC stored canonical 11-digit (segment-aware); ndc_raw preserves the source dashed form.
Note	The drug-identity NDC<->HCPCS bridge (2026-07-14). Unified the previously-disjoint drug + medical graph components — see docs/architecture/2026-07-14-source-connection-node-graph.md. One J-code -> many NDCs.
